[Bug 1065331] [NEW] variables defined in maintanier script overriden by global config

[Marcin Antczak]

Public bug reported:

This is an upstream bug.

Currently in /usr/share/dbconfig-common/config file there is function
called dbc_go()

This function calls dbc_config $@ few times (Lines 10 and 163).

dbc_config loads global configuration file for dbconfig-common localized
in /etc/dbconfig-common/conf

Values from this file override these provided by package maintainer in
package.postinst etc.

This is unusual and in my opinion wrong behavior.

For example - maintainer wants to avoid dependency on mysql-server
package and wants to enable an ability to configure package with
dbconfig-common and remote connection to some mysql-server on remote
host.

Then in package.config:

    dbc_remote_questions_default='true'
    
    . /usr/share/dbconfig-common/dpkg/config 
    dbc_go dbconfig-test $@

Unfortunately true for dbc_remote_questions_default is overriden if set
in global /etc/dbconfig-common/conf because this config is executed
directly from dbc_go
